WILLIAM KOPISOH, OF BLUE HILL, NEBRASKA.

DOOR-HANGER.

SPECIFICATION forming part of Letters Patent No. 391,053, dated Qctober 16, 1888.

Applicatirn filed June 2, 1888. Serial No. 275,863.

To all whom it may concern.-

Be it known that 1, WILLIAM KOPISCH, a citizen of the United States, residing at Blue Hill, in the county of WVebster and State of Nebraska, have invented new and useful Improvements in Door-Hangers, of which the following is a specification.

My invention relates to improvements in door-hangers, having for its object to simplify, improve, and strengthen the construction and reduce the friction of running, whereby the ease of operation and durability are increased.

The invention consists in a certain novel construction and arrangement of devices, fully set forth hereinafter, in connection with the accompanying drawings, wherein- Figure l is a front view of the hanger applied to a portion of a door. Fig. 2 is a central transverse sectional view. Fig. 3 is a central longitudinal sectional view. Fig. 4 is a detail side View, partly in section, of the hangerbracket, with the adj usting-bar released at its free end to allow the rollers to be inserted.

Referring to the drawings, A designates the loop-shaped hanger-bracket, which is secured at its lower end to the door and is provided at its upper end with the yoke B, which is provided in its under side with the longitudinal slot or recess 0. The lower edge of the yoke is provided on each side of the center with the bearings D D, and the anti-friction rollers E E are arranged in the recess or slot and provided with lateral trunnions F F, which are mounted in the bearings D.

The track G is provided with the central guiding-rib, H, and I I designate the running rollers, which bear on opposite sides of the rib and are connected by the rigid (and preferably integral) axle K. The anti-friction rollers E E bear on the axle between the running rollers, and the inner sides of the lastnamed rollers are provided with the guidecheeks L L, which hold the anti-friction rollers at the center of the axle. These cheeks are rigid with the axle and the rollers I.

(No model.)

It will be seen that the weight which is supported by the hanger-bracket is carried by the axle, so that when the door is moved laterally the running rollers move along the track and the anti-friction rollers operate on the axle, and to prevent the said antifriction rollers from becoming dismounted from the axle the bar M is arranged under the axle and provided with a central bearing, N, to receive the same. One end of this bar is pivoted to the under side of the yoke and the other end is provided with an aperture, 0, to receive the lower end of a depending threaded bolt, P, on the other end of the said yoke. The extremity of the bolt which projects below the said bar is engaged by the nut R, whereby the end of the bar may be raised or lowered to alter the height of the bearing N. This adjustability of the bar M enables the anti-friction rollers to be always held in contact with the axle of the running rollers, and as the rollers or the axle or any other parts of the device become worn the said bar is raised to compensate for the wear.

Having thus described te invention, I claim- In a door-hanger, the combination, with the running rollers connected by arigidaxlc, of the bracket having anti-friction rollers mounted thereon and bearing on the said axle, and the bar pivoted at one end to the bracket and mounted at the other end on an adj usting-bolt, the upper side of the bar being provided with a bearing to receive the said axle, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in pres ence of two witnesses.
